We’re told the Migos rapper is giving the “I Like It” rapper a necklace, charm bracelet and Kulture’s name emblazoned on a set of earrings. Offset reached out to Pristine Jewelers’ owners Avi and Ofir 2 months ago to plan something special for Cardi’s 26th birthday.

The 3 pieces are 100 carats strong in diamonds. Offset flew out the jewelers to personally hand over the cache to Cardi … who couldn’t contain herself and flaunted the sparkle at parties last weekend.

Cardi also sported the new bling Saturday night when she performed at Drake’s concert. All in all … we’re told Offset dropped over six figures. And, that’s just the tip of the birthday iceberg. Remember … Offset also gave Cardi a Lambo earlier this month.
